Build a bikeway so two people can cycle side-by-side to have a pleasant chat.

I want this for Chicago. When you ride with friends, how would you prefer to ride: yelling ahead in our narrow bike lanes or conversing to the side? This is sometimes possible on the Lakefront Trail, but not always: the Lakefront Trail’s maximum width is the same as the standard with for cycle tracks in Europe!

Bike lanes in the United States, when they’re available and not being parked in, are not even wide enough for one person to ride without danger of being doored. It’s not surprising this is the case. In addition to how we prioritize the movement of automobiles and the placement of parking before pedaling, the national minimum width for a bike lane is 4 feet (without gutter), or 5 feet when next to parked cars or with a gutter.

I gathered some hard evidence: My handlebars are 28 inches wide. The door of my roommate’s car is 32 inches wide. 28+32 = 60 inches, or 5 feet. And that’s without a buffer. Essentially, bike lanes as we’ve built them are not compatible with the rest of the street.
